doc-number is generally provided in DOCDB-normalized format.

Patent document numbering is a complex subject, as the examples below illustrate:

kind13

The kind code is used to designate the publication stage of the document, including whether it is a published application or a granted patent. See ST.16.

Note that some documents (utility models, reissued patents, etc.) contain non-standard kind codes used by various patent-granting authorities. See the Kind Code Concordance List for a list of many of the kind codes corresponding to the different publication stages of a patent application.

date14Date of publication (YYYYMMDD)
Note: If no date is present and a document-id element exists, a default value of 00010101 (which may appear as 10101) or 19000101 is inserted. The 00010101 date is available in Solr responses only and is not present in the XML.
lang12Original language of publication, 2-character code based on ISO 639-2.
Note: The default value is "XX" if no language information is provided by the data source.
